How would changing the size of the receptive fields of somatic neurons in the arm increased affect the acuity of sensation?
A) larger receptive fields increase acuity
B) smaller receptive fields increase acuity
C) smaller receptive fields decrease acuity
D) changing receptive field size has no affect on acuity, only the sensitivity of the neuron determines acuity

Question

Smaller receptive fields increase acuity because they allow for more precise localization of stimuli. With smaller receptive fields, each neuron responds to a smaller area of the skin, resulting in a more precise map of where a stimulus is located on the skin. This leads to higher acuity, or the ability to discriminate between closely spaced stimuli.
